Abstract

PROBLEM TO BE SOLVED: To provide a train monitor equipment which can detect correct mileage, even while the train is running between stations. SOLUTION: This equipment corrects the mileage calculated by counting pulse signals from a speed generator 13, based on the preliminarily stored mileage for each station after confirming the stops of the train at the station by signals from a door-close relay 15. For that purpose, this equipment is provided with a mileage correcting means 17a which ascertains that the train has passed a block section by detecting the change in ATC carrier wave signals from an ATC receiver 16 and then corrects the mileage, while a train 11 is running between stations, based on the preliminarily stored mileage for each block section.
